Capital B Wins EUR 5B Dilution Authority for Bitcoin Buys

Shareholders approve massive financing capacity as European treasury firms race to scale holdings

Capital B shareholders approved up to EUR 5 billion in capital increase authority and EUR 100 billion in credit instrument authority at an annual general meeting on June 17, 2026, expanding management’s optionality to fund Bitcoin acquisitions without returning to shareholders for each transaction.

The approvals grant Capital B’s board discretionary power to issue equity or debt instruments at future prices and terms of management’s choosing. The distinction matters: authorization capacity does not commit the company to any specific financing, but it removes the need for shareholder consent between now and the next annual meeting. Capital B announced a EUR 300 million plan on June 9 to increase its Bitcoin acquisition capacity, signaling near-term deployment intent.

Capital B’s strategy centers on a metric that will define shareholder returns: Bitcoin per fully diluted share. “Bitcoin Treasury Company strategy focuses on increasing the number of BTC per fully diluted share over time,” the company stated. That objective depends on how many new equity claims and debt instruments Capital B layers atop existing shareholdings. Each issuance or borrowing affects the denominator. Management describes accretion as a goal rather than a guarantee, introducing execution risk for current holders.

BTC AB Tests Preference-Share Demand in Sweden

Across the Atlantic, BTC AB is executing a smaller but structurally complex capital raise. The company opened a preference-share rights issue on June 16, 2026, targeting SEK 23.4 million before costs. Specifically, BTC AB is offering 195,078 Class A preference shares at SEK 120 per share. Existing Class B shareholders received one subscription right for each share held on the June 12 record date; four rights entitle holders to one preference share.

BTC AB’s preference structure introduces layers absent from common equity. In particular, preference shares carry fixed dividends, redemption mechanics, and payment priority that existing Class B shareholders do not enjoy. “The issue is intended to strengthen the capital base and support continued execution of its Bitcoin treasury strategy,” BTC AB said. The subscription period closes June 30, 2026, with trading in preference shares estimated to begin July 20, 2026.

Insider support for the BTC AB raise remains partial. Board members and management disclosed SEK 2.4 million in non-binding subscription intentions, covering 10.2% of the issue. By contrast, subscription undertakings, which are binding, reached SEK 6.4 million, or 27.2% of the total. That leaves 62.6% of the rights issue dependent on market demand from external investors.

BTC AB held 171.33 Bitcoin as of May 27, 2026. That translated to 0.00021957 Bitcoin per B-share on a fully diluted basis. The preference-share issuance will dilute that ratio unless Bitcoin price appreciation or additional Bitcoin acquisitions offset the new claims.

European Bitcoin treasury companies are increasingly layering debt, preferred equity, and at-the-market issuance mechanisms. The goal is to scale holdings while managing equity dilution. For instance, Capital B’s EUR 100 billion credit instrument authorization signals willingness to use leverage. The company has not disclosed the terms, interest rates, or repayment schedules for those instruments, leaving the debt component of its capital structure opaque to public shareholders.

Both companies face a shared challenge: sustaining Bitcoin per share growth in a competitive market where peers are also issuing equity and debt to buy Bitcoin. Execution timing, pricing discipline, and Bitcoin price movement will determine whether these authorizations create value or dilute existing holders.
